Powershell vs WMI

[jip31]

Hi

But i would prefer to do it with PowerShell but the script display any fiels (it works perfectly alone)
Find below what i have done :
COMMAND OR SCRIPT PATH
. "$SplunkHome\etc\apps\Splunk_TA_windows\bin\videosignal.ps1"
CRON

SOURCETYPE
powershell:videosignal

POWERSHELL SCRIPT:
$strComputer = "."

$objWMi = get-wmiobject -computername localhost -Namespace root\CIMV2 -Query "Select * from Win32_DesktopMonitor"

foreach ($obj in $objWmi)
{
write-host "Availability:" $obj.Availability
